Application october s, v1932. serai No. V635,891 z claims. (o1. zes- 585 The main objects of this 'invention' are: L'

First7 to provide an .atomizer or sprayer by means of which a liquid such as watermay be eectively atomized and discharged in a mist- 5 like spray which is substantially free from particles of water which would fall' as drops.

Second, to provide an'atomizer or spray apparatus which is well adapted for use in'connection .with vegetable stands or display racks and for maintaining a mistlike p spray which has been found tobe highlyeliective in keeping vegetables and fruitsv in a desirableA condition and reducing thetemperature of the surround ying atmosphere.

Third', to provide an apparatus of this character whichmay be easily adjusted to regulate the i lquantity of `water discharged and the character fofy the spray. 1 Fourth', to'prcvide an apparatus having these 5 20 advantages 'which may be easily' adjusted by persons not skilled as mechanics.

Fifth, to provide an.` apparatus which main-y valve being shown in full lines.

Fig. 3

is a horizontal section on line 3-3 of Fig. 1.

lv is a horizontal section on line 4-4 of Fig. '1. Y Fig. 5 is a reduced fragmentary vperspective view of the base oi the unit.

In the embodiment illustrated in the accompanying drawing 'providean inverted channellike base l which is mounted on a supporting bracket or hanger 2 having laterally projecting flanges 3 and a central opening 4 adapted to receive the casing 5. The pipe coupling 50 having 'M lateral ears 6 is mounted on the base 1 andre.- ceives the vertical supply pipe 7 which constitutes a supporting standard. The coupling 50 is adapted to be connected to a suitable V source of water supply.

On the upper end of the pipe l is a coupling head 8 havinga cylindrical enlarged portion 10 embraced by and constituting a support for the casing,v the casing enclosing this coupling head. The head is provided with an upwardly facing central socket l1 having an outlet or drain passage -12 discharging within the casing 5A which constitutes a drain conduit. The tubularsupport 13 is threaded into ythe socket l1 and Ais provided with a longitudinal drain slot 14 at its upper end. H I

An atomizing disk 15 is seated upon the upper end or" the drain pipe and has a depending central stemv l5 which is recessed within the `pipe .for positioning and retaining this disk. The sleeve-like combined drain cup and baille member'l'? isthreaded upon the support i3 for substantial longitudinal adjustment thereon, lthe upper or cup-like portion 18 of this member surrounding the atoniizing disk 'in spacedconcentric relation thereto. This combined baiile and drain .member collects 4the'imatomized water particles 'and the larger particles, according to its adjustyment rrelative to the impact or atomizing disk,

The head 10 in the embodiment illustrated provided with a pair of upwardly facing sockets 19 and 20', the socketl) being connected to the supply pipe by a passage 2l.- Bowed arms 22 and 23 `are 'Y mounted in these sockets to provide a "A yokedike support for the T-shaped body member l removably arranged within this tubular or cylindrical portion -25 of the nozzle body member and has-an outwardly extending ange 28 at its router end which engagesthe end oi the body U member when it is forced into position by the packing ring 29 disposedwithin the gland. The

outer and larger portion 30 of the bore or this valve member is internally threaded to 'receive the externally threaded tubular nozzle ,member I' provide a needle valve 32 having a stem 33, the upper` end of which isfrictionally mounted in the reduced borefl at the `inner end of the valve member, the lower end of which is procenteringY bearing or support for the needle Valve head 35. At the outer end of its `bore 40 the nozzle member has a transverse partition 4l with a central port 42 with which the needle valve 32 coacts. Below this partition the nozzle member has an enlarged chamber 34 terminating in discharged from theV disk 15.

a flared mouth 44 so that the jet is projected from the nozzle without contacting withV any part and 'is effectively protected. The jet may be varied by adjusting the nozzleto open or close the needle valve. l

The valve is effectively heldin central or concentric relation lrelative yto the Walls of the nozzle port so that a perfect stream or jet is discharged and one that is. properly directed to strike centrally of the atomizingdisk. vAs stated, byadjusting the member 17 the character lof thev spray is under effective control, .that is,A the nozzle may be accurately adjusted to control the amount of Water delivered .by the needle valve to thedisk 15, and the member 17 may be adjusted to control theamount and character of the spray As a matter of fact, the spray may be so finely 'atomized as to constitute a foglike mist which forms and maintains a blanket of cool moist air above the ,vegetables or fruits when the device is used in that relation,vand it is found to'very materially reduce the temperature withina substantial area.

yIt is also found that equipment having my im-Y provements embodied therein is highly effective in keeping vegetables and similar green products displayed in stores in a fresh desirable condition.

' The apparatus has the very'material advantage' which has been found very satisfactory in use. I have not attempted to show other adaptations of which my invention is capable as it is believed this disclosure will enable the adaptation thereof by persons skilled in the art.

Having thus described my invention what I claim as new and desire Ato secure by Letters Patent is: f

l1. In an atomizer, the combination of a supply pipe, a coupling head on the upper end of said supply pipe having a central threaded socket and va drain passage leading from said socket to the side .of ysaid head, said head having a pair of arm sockets, one of said arm sockets being connected to said supply pipe, a casing surrounding said supply pipe and head, avsupport mounted in said threaded socket and supplying a drain passage, an atomizer disk mounted in said support, a combined drain cup and baffle threaded upon said support for adjustment thereon relative to said atomizing disk, bowed arms mounted in saidV arm sockets', one of said arms constituting a water delivery pipe, a coupling connecting said arms, and anozzle mounted on said coupling to dischargea jet of water upon said disk.

2. A vaporizing device comprising a Water supply pipeconstituting a standard, a head mounted upon said supply pipe, a yoke-like nozzle support mounted on said head, one ofthe arms ofsaid .support constituting a conduit, said head having a passage connecting said conduit to said supply pipe, a downwardly directed nozzle mounted on said nozzleV support, a tubular atomizing disk support mounted centrally on said head in alinement with said nozzle, a circular atomizing disk mounted on said support 'in alinement with said nozzle, a combined draincup and baflle member threaded upon said disk support for adjustment relative to saidatomizing disk, lsaid disk support having a drain opening therein, said head memberhaving a drain passage communicating with said drain opening, and a tubular casing enclosing'said supply pipe and head member in supporting engagement Vwith the latter;
